Anyone who has tried to connect a GoPro or DJI Action camera to the Quik or Mimo app under water knows the frustration. WiFi does not travel through water, so the connection drops as soon as the camera goes below the surface. The Seavu Seeker Marine Kit provides a true underwater WiFi extension cable solution so you can see, control, and record live footage on your phone or tablet.
Why WiFi fails under water
Wireless signals like WiFi and Bluetooth are quickly absorbed by water. Even a few centimetres of depth can break the connection between your camera and mobile device. For years, people filmed blindly and checked footage later. The Seeker Marine Kit changes that by extending the signal to the surface. For background on signal behaviour in water, see this explainer from NOAA.
The Seeker Marine Kit: built for underwater connection
The Seeker Marine Kit is more than a cable. It is a complete communication system designed for saltwater use.
How it works
- The Seavu transmitter captures your camera WiFi and Bluetooth signals under water.
- A custom low loss tether carries that signal through the water to your receiver.
- The Seavu receiver rebroadcasts it wirelessly to your phone or tablet.
This gives you real time live view, camera control, and recording through the normal app, even when the camera is many metres under water.
Why it beats other underwater WiFi cables
- Purpose built tether cable that is flexible, marine proof, and designed for long distance signal integrity.
- Versatile mounting system to easily attach to poles, rigs, burley pots, and custom setups.
- No hard connections to camera or phone, which reduces corrosion risk in marine environments.
- Future proof design that works with the latest GoPro HERO13 Black and DJI Osmo Action 5 Pro, with a clear upgrade path for new models.
Live underwater viewing with Quik or Mimo
- View and record live underwater footage in real time.
- Adjust camera settings, switch modes, start and stop recording.
- Monitor footage on your phone or tablet using GoPro Quik or DJI Mimo.
Trusted for reliability
The Seeker Marine Kit is used by researchers, filmmakers, educators, and recreational users worldwide. It is designed and tested in Australia and proven in saltwater. Leading research organisations such as the Australian Institute of Marine Science and CSIRO employ similar underwater monitoring approaches for ocean studies.
